The Math of "The Martian" Sol 71

Mark is planning on testing his long distance modifications to the Rover with a long distance trip. 

The Hab is located at 31.2 degrees north, 28.5 degrees west. He plans to go to 19.13 degrees north, 33.22 degrees west, and back. How far is that? How many Sols will the trip take? 

The Rover’s Oxygen tanks hold enough for 7 Sols. If Mark needs 588 Liters of gaseous Oxygen per Sol, how much liquid Oxygen does he need to make up the difference? If the Hab has two 25 Liter liquid Oxygen tanks, will he need to take one or both?


His potatoes aren’t ready to harvest yet, so he will need to take ration packs with him. What is the minimum amount of packs that he will he need to take?
